DETAILED DESCRIPTION OF THE INVENTION

In the present invention, the term “photo album” refers to a book that includes one or two cover pages and one or more image pages. Each of the image pages can include one or more images. The image pages can also include text or image caption. The image layout can also include a background pattern. In the imaging industry, photo albums can include photo books, scrapbooks, snap books, and any books form including bound image pages.

A computer system 100 illustrated in FIG. 1 represents an exemplified hardware setup for executing software that allows a user to perform tasks such as communicating with other computer users, accessing various computer resources, and viewing, creating, or otherwise manipulating electronic content, that is, any combination of text, images, movies, music or other sounds, animations, 3D virtual worlds, and links to other objects. The system includes various input/output (I/O) devices (mouse 103, keyboard 105, display 107) and a general purpose computer 100 having a central processor unit (CPU) 121, an I/O unit 117 and a memory 109 that stores data and various programs such as an operating system 111, and one or more application programs 113. The computer system 100 also typically includes non-volatile memory 110 (e.g., flash RAM, a hard disk drive, and/or a floppy disk or other removable storage media) and a communications card or device 123 (e.g., a modem or network adapter) for exchanging data with a network 127 via a communications link 125 such as a cable modem, DSL service or wireless Internet connection.

The computer 100 of FIG. 1 also can be connected to various peripheral I/O devices. One of the more popular of such peripheral devices is a digital camera 108. The digital camera 108 enables users to take pictures (i.e., images), which are saved in memory (not shown) within the digital camera 108 in a digital (electronic) format. After taking and storing the images, the user can connect the digital camera 108 to a computer system 100 in order to upload the digital images to the computer's disk drive or other non-volatile memory 110. The user can also wirelessly transfer digital images in the digital camera to the computer system 100. Once the digital images are uploaded to the computer system 100, the user can erase the digital images from the memory of the digital camera 108 so that the user can take and store additional images using the digital camera 108. Typically, the digital camera 108 is connected to the computer 100 only while the user is uploading images to the computer's disk drive or other non-volatile memory 110.

Users also can obtain digital images, for example, of film-based prints from a traditional camera, by sending an exposed film into a photo-finishing service, which develops the film to make prints and then scans (or otherwise digitizes) the prints or negatives to generate digital image files. The digital image files then can be transmitted back to the user by e-mail or on a CD-ROM, diskette, or other removable storage medium.

Once the digital images are stored on the computer 100, a user can perform various operations on them. For example, an image viewer application can be used to view the images. A photo editing application can also be used to touch-up or otherwise modify the images. In addition, an electronic messaging (e.g., e-mail) application can be used to transmit the digital images to other users.

In addition to viewing the digital images on the computer display 107, users often desire to have physical products based on the digital images. Such hard copies can be generated locally by the user using output devices such an inkjet printer or a dye sublimation printer 130 or remotely for a photo printing service provider. Other products based on the digital images can include photo books, photo calendars, photo mug, photo T-shirt, and so on. A photo book can include a cover page and a plurality of image pages each containing one or more images. Each page can also include different formats. Designing a photo album can include many iterative steps such as selecting suitable images, selecting layout, selecting images for each page, add text, which can be quite time consuming. It is desirable to provide methods for designing and producing photo albums that can substantially save a user's time. FIGS. 2A and 2B shows an exemplified photo album 200 comprising a plurality of many pages 210, each including one or more images 220 provided by a user. The user can select a layout for each page and select images 220 for each page.

Referring to FIG. 3A, a photo album can be created in the following steps: images can be captured by taking pictures using a digital camera, copying existing images through the Internet, or by any other methods. The captured images are then transferred to a computer and stored in a memory on the computer (step 310). A user selects a list of images on the computer system 100 to be used in a photo album (step 320). Referring to FIG. 4, a collection 400 of images is shown in a graphic user interface as candidates to be incorporated into a photo album. By clicking on the small square below each of the images, the images can be selected into an image list 500 (shown in FIG. 5). More images can be viewed and selected into the image list by clicking a “next page” button 410 or a “previous page” button 420.

Referring to FIG. 5, an image list 500 can therefore created by the user. The user interface in FIG. 5 shows an array of thumbnail images that represent the original images (i.e. full size images) provided by the user. The image list 500 can reside on different view fields which can be viewed by clicking the “next page” button 510 or the “previous page” button 520. In some embodiments, the image list 500 can be sequenced in a same order as how they will be incorporated into a photo album. The sequence of images in the image list 500 can chronically ordered by capture time. Alternatively, the images can also be grouped and ordered by events and activities, which may be optimal for telling a story using the photo album.

Referring back to FIG. 3A, a user can select the images to be displayed on a page of the photo album in a number of different ways. For example, referring to FIG. 7A, a user can select, by clicking a button on a user interface, how many images are to be displayed on the next page of a photo album. For example, there can be one, two, and three images on a page. The number of images per page can vary in a photo album. In some cases, a user may select a constant number of images for each page of a photo album.

In another example, the image list 500 (FIG. 5) can be separated by page groups. As shown in FIG. 7B, images 731-735 that represent the original images in the image list 500 can be graphically grouped in two page groups: Page 10 and Page 11 in a graphic user interface 700. The images 731, 732 in Page 10 can be surrounded by a border 740 to clearly separate them from the images 733-735 that are positioned within a border 741. Each page can include different numbers of images, and different types (portrait, landscape, round, oval, diamond, square, etc.) images. A landscape format describes images that have longer lateral dimensions than their vertical dimensions. A portrait format refers to images that have longer vertical dimensions than lateral dimensions. A user can flexibly move images 731-735 between different page groups. Buttons 710 and 720 can help a user to browse all the pages in the photo album.

A user can readily re-arrange images between different pages using the user interface shown in FIG. 7B. For example, a user can move image 732 from page 10 (within border 740) to page 11 (within border 741). The user can also move image 733 from page 11 (within border 741) to page 10 (within border 740). The user can easily add or remove images from the borders 740 or 741 and the pages they respectively represent by moving images from or to the image list. The number of images within each border and their associated pages can thus be easily adjusted by the user. The page layouts, as described below, can be automatically selected in response to the dynamic changes in the image compositions in the borders 740 and 741.

Referring back to FIG. 3A, a library of page layouts are provided for creating pages in a photo album (step 315). A page layout defines one or more image areas on a page in the photo album. An image area can have a rectangle shapes such as landscape or portrait format, or square. An image area can also have round, shape, diamond, or other shapes. A page layout can have different numbers of images which may have different combinations of landscape and portrait formats for the image areas.

FIGS. 6( a) to 6(i) illustrate exemplified page layouts for a photo album. The page layout shown in FIG. 6( a) contains a single image area 611 for receiving an image in landscape format. FIG. 6( b) shows a pay layout containing an image area 612 suitable for a portrait image. A page layout in FIG. 6( c) includes portrait image areas 621 and 622, while the page layout in FIG. 6( d) contains landscape areas 623 and 624. FIG. 6( e) shows a layout that includes a portrait image area 625 and a landscape area 626. FIG. 6( f) shows a pay layout having three landscape areas 631, 632, and 633, while FIG. 6( g) shows three portrait areas 634, 635 and 636 in a page layout. FIG. 6( h) shows two landscape areas 637, 638 and a portrait area 639 in a page layout. FIG. 6( i) shows two portrait areas 641, 642 and a landscape area 643 in a page layout.

In accordance with the present invention, the disclosed system and methods can automatically select a page layout from the library of page layouts in accordance to the properties of the images to be displayed on a page (step 330). For each page in the photo album, the page layout selected from the library of page layouts should include the same number of images to be displayed on the next page. The page layout selected should also include the same numbers of portrait and landscape image areas as the numbers of portrait and landscape images to be displayed on the next page.

Since it is desirable to provide a large number of page layouts, multiple page layouts in the page layout library may satisfy the number and format of the groups of images to be displayed on the next page. For example, five page layouts may exist that all include two image receiving areas with one portrait and one landscape format, as required by the group in Page 10 (shown in FIG. 7B). An algorithm stored in the computer or at a remote server can automatically select one of the multiple choices from the satisfactory page layouts. For example, the most popular page layout among five satisfied page layouts can be selected. The user can change the page layout later when the user fine tunes the designs of the photo album.

Once an appropriate page layout is selected for the images to be displayed on the next page, referring back to FIG. 3A, the selected images can be automatically placed onto the selected page layouts to create pages (step 335). Image cropping may be needed in some situations when the aspect ratio or shape of an image receiving area in a page layout does not exact fit a selected image. The image cropping can be automatically conducted by a computer or determined by a user.

An electronic file containing the designs for the photo album can be produced and stored on the computer 100 (step 340). A physical (i.e. hardcopy) photo album (or photobook) can be manufactured by a digital printer and other finishing equipment in accordance to the designs defined by the electronic file.

Other detailed examples about the selections of images for a page and the subsequent automatic selection of page layout (steps 325 and 330) are illustrated in FIGS. 8-11. In FIG. 8, a single picture is selected for a page. The image list and the library of page layouts are provided (steps 801 and 802). The disclosed system can automatically select from the top of the image list 500 (step 803). The selected image is removed from the image list 500 (step 804). The format of the selected image is next checked (step 805) if it is of a landscape or a portrait format, or other shapes such as round, oval, diamond, etc. If the selected image has a landscape format, the image is dropped in the image area 611 of the page in FIG. 6( a) in step 806. If the selected image is portrait, the disclosed system drops the image in the image area 612 of the page in FIG. 6(2) in step 807. In step 808, the disclosed system adds the page that has just been processed in either step 806 or step 807 to the photo album 200 that is being created. In step 809, the disclosed system checks if the image list 500 is empty. If the image list 500 is empty, it means all images in the list have been added to the photo album 200. The disclosed system then saves the complete photo album 200 on the computer. The photo album can be produced by a digital photo printer and other equipment (step 810). If the image list 500 is not empty, there are unused images on the list to be added to the photo album 200. In this case, the disclosed system goes back to step 803 to select the next available image at the top of the image list 500. This loop is continued until all images in the image list 500 are used and added to the photo album 200.

In FIG. 9, two images are selected to be displayed on a page of the photo album. The disclosed system selects up two images from the image list 500 to dispose in the image areas (step 903). The selected images are removed from the image list 500. In step 905, the disclosed system checks if the two selected images are both landscape images. If they both are, the disclosed system randomly drops the two images into image areas 623 and 624 in FIG. 6( d). If the check in step 905 is “No”, the disclosed system checks in step 906 if both selected images are portrait images. If they both are portrait images, the disclosed system randomly drops the two images into the image areas of 621 and 622 in FIG. 6( c). If the check in step 906 is “No”, the only possibility is, one of the selected images is landscape image and the other is portrait image. In this case, the disclosed system drops the portrait image in the image area 625 and the landscape image in the image area 626 in FIG. 6( e) in step 909. When either steps 907, 908 or 909 is finished, the disclosed system, in step 910, adds the page created in either steps 907, 908 or 909 to the photo album 200 that is being created. Then in step 911, the disclosed system checks if the image list 500 is empty. If the image list 500 is empty, it means all images in the list have been added to the photo album 200. The disclosed system then sends the complete photo album 200 to a digital photo printer to print out the photo album in step 912. If the image list 500 is not empty, there are unused images on the list to be added to the photo album 200. In this case, the disclosed system goes back to step 903 to select the next two available images at the top of the image list 500. This loop is continued until all images in the image list 500 are used and added to the photo album 200.

When the computer system picks up the next two available images from the image list 500. Toward the end of the image list 500, there can be either one image left in the image list 500, or there can be two. If two images remain in the image list 500, the disclosed system picks up the last two images finishes the photo album (step 912). If the image list 500 only includes a single remaining image, the disclosed system picks up the last image and treats the second empty image as having the same format as the last available image. The final finished photo album 200 can have an empty image area on the last page. The disclosed system can also automatically adjust the last page to include only one image receiving area.

In FIG. 10, three images are selected to be displayed on a page of the photo album. An image list 500 and a page layout library are first taken by the disclosed system (not shown in FIG. 10). In step 1003, the disclosed system selects up three images from the image list 500. The selected images are then removed from the image list 500. In step 1005 the disclosed system checks if all three selected images are of landscape format. If the check 1005 is “Yes”, the disclosed system randomly drops the three selected images into 631, 632 and 633 of FIG. 6( f). If the check 1005 results in “No”, the disclosed system checks, in step 1006, if all three selected images are of portrait format. If the check 1006 results in “Yes”, the disclosed system, in step 1009, randomly drops the three selected images into 634, 635 and 636 in FIG. 6( g). If the check 1006 is “No”, the disclosed system, in step 1007, checks if two of the three selected images are of landscape format and the third selected image is of portrait format. If the check 1007 results in “Yes”, the disclosed system, in step 1010, drops randomly the two landscape images into 637 and 638 and the one portrait image in 639 in FIG. 6( h). If the check 1007 results in “No”, the only possible combination is that two of the selected images are portrait images and the third one landscape. The disclosed system, in step 1011, randomly drops the two portrait images into 640, and 641, and the landscape image in 642 of FIG. 6(I). With either of the steps 1008-1011 is finished, the disclosed system adds the current page to the photo album 200 in step 1014 followed by a check 1012 to see if the image list 500 is empty. If the check 1012 is “Yes”, all images in the image list 500 have been added to the photo album 200, and the disclosed system sends the photo album to a digital printer in step 1013. If the check 1012 results in “No”, there are unused images in the image list 500, and the disclosed system goes back to step 1003. This loop is on until all images in the image list 500 are used in the photo album 200.

As the image list may emptied out as pages in the photo album is filled. There may be 1, 2 or 3 remaining images in the image list 500. In the case there are three remaining images in the image list 500, the disclosed system goes through the ordinary process and selects the last three images. In the case that there is one remaining image in the image list 500, there are two possibilities. If the remaining image is landscape, the disclosed system produces the last page of the photo album 200 using the page layout of FIG. 6( f), with 631 filled with the last image in the image list 500, and 632 and 633 empty. If the remaining image is portrait, the disclosed system produces the last page of the photo album 200 using the page layout of FIG. 6( g), with 634 filled with the last image in the image list 500, and 635 and 636 empty. In the case there are remaining images in the image list 500, there are three different situations. (1) Both of the remaining images are landscape images. (2) Both of the remaining images are portrait images. (3) One of the remaining images is landscape image and the other portrait. For situation (1), the disclosed system uses the page layout of FIG. 6( f), filling 631 and 632 with the two remaining images, and leaving 633 empty. For situation (2), the disclosed system uses the page layout of FIG. 6( g), filling 634 and 635 with the two remaining images, and leaving 636 empty. For situation (3), the disclosed system used the page layout of FIG. 6( h), filling 637 with the remaining landscape image and 639 with the remaining portrait image and leaving 638 empty. For the cases where there are one or two empty image areas in the last page of the photo album 200, the user can either leave the finished photo album 200 as it is, or manually fill the open image area(s) with additional image(s).

A user can also select different numbers of images for a page in the photo album, such as a combination of one, two, or three images per page, as shown in FIG. 11. In step 1103, the disclosed system randomly selects a number among 1, 2 or 3 for the number of images on the current page of the photo album 200 that is being created. After the number of images is selected, the disclosed system selects that number of images from the image list 500. The selected images are then removed from the image list 500 (step 1104). The disclosed system then checks if a single image has been selected (step 1105). If the result is “Yes”, the selected image is dropped in the current page (step 1107) (which can include steps 805, 806, and 807 as shown in FIG. 8). If the result is “No” in step 1105, the disclosed system further checks if two images have been selected (step 1106). If the check 1106 results in a “Yes”, the disclosed system drops the two selected images in the current page in step 1108, which includes steps 905-909 in FIG. 9. If the check 1106 results in a “No”, three images must have been picked. In this situation, the disclosed system drops the three selected images to the current page in step 1109, which includes steps 1006, 1007, 1009-1011 in FIG. 10. After either of steps 1107, 1108, or 1109 is finished, the disclosed system adds the current page to the photo album 200 in step 1110. Then the disclosed system checks in step 1111 if the image list 500 is empty. If the image list 500 is empty, all images have been added to the photo album 200. The disclosed system sends the photo album 200 to a digital printer in step 1112 to print out a hard copy of the photo album. If the image list 500 is not empty, there are unused images remaining to be added to the photo album 200. The computer goes to step 1103 and select more images to process. The loop can continue until all images in the image list are incorporated into the photo album 200.

The page layouts can include text field for receiving text from user. The text can be image caption associated with each image on the page. The text can also be a general caption on the page. The text can include a title for the front or cover page of the photo album. As shown FIGS. 12A and 12B, captions area 1201 and 1202 is provided in page layouts next to their respective image receiving areas 1203 and 1204. A page layout can also be featured with some pre-defined background images. For example, FIG. 13A has a background 1301 with a house, some cloud and a sun in the ski, while FIG. 13B has a background 1302 with some balloons. The user can change the background for each and every page of the photo album 200. The background images can also be automatically selected by the computer in response to the image content, the title of the photo album or the captions for the images entered by the user.

In some embodiments, referring to FIG. 3B, after a list of images is selected (step 360), text information can be entered by the user in association with an images in the image list (step 365). The text information can include description or remarks about an image. The text associated with an image is stored as an integrated data structure in a computer memory. When an image is selected from the image list (step 370), the text information associated with the selected image is automatically captured together with the selected image. A library of page layouts are separately proved (step 372). Next, a page layout is automatically selected from the library of page layouts in accordance with the properties of the images on the page as well as the text information associated with the image receiving areas in the page layout (step 375). The format of the image receiving field in the page layout matches the format of the selected image. The page layout also includes an image caption area positioned adjacent to the image receiving area for receiving the associated text information. For example, one portrait image and one landscape image may be selected for the next page. The portrait image has associated text information entered by the user and stored in conjunction with the portrait image. The landscape is not associated with any text information. In selecting a page layout, the disclosed system first select page layouts containing two image receiving areas, and then further selects page layouts that have include one portrait and one landscape image receiving areas. Additionally, the disclosed system further selects page layouts that include an image caption area in association with the portrait image receiving area. After the page layout is selected, the selected image(s) and associated text are automatically placed in the selected page layout (step 380). The placement of the selected image(s) and associated text can be done in a single step because they are pre-stored in an integrated data structure as described previously. The same steps can be repeated for fill the image fields and text fields in each page of a photo book to create the photo book (step 385).

In some embodiments, referring to FIG. 14, a plurality of images is stored on a computer system (step 1410). The images can be first sorted by a computer system based a primary criterion (step 1415) to produce a list of sorted images. The images are sorted by a predetermined primary criterion based on the likely sequence that the images will be presented in a photo book (step 1415). For example, the images can be sorted by their associated image capture times. The image capture times can be extracted from the header information in the image files. For example, a JPEG image may include an EXIF header that includes the capture time of the image. It is stored by the digital camera in the image file as information in association with the image data. Referring to FIG. 15, a cumulative image count can be plotted against image capture time. In one implementation, the list of sorted images can be sequenced chronically based on capture time of the images. Users often prefer to have images to appear in book pages in a chronicle order.

The list of sorted images is then separated into page groups by a computer system using one or more secondary criteria (step 1420). For example, images can be grouped according to the capture times. Images captured in a short time interval are more likely suitable to be placed on the same page, facing pages, or adjacent pages in a photo book. In some embodiments, images that are taken in a short interval (e.g. a day) can be assigned to a same group (e.g. Group A, FIG. 15). The images in Group A, Group B, or Group C (FIG. 15) are captured in a short time interval. The images in each of these groups can be respectively grouped as candidates to appear on a same page, facing pages, or adjacent pages.

The sorted images may be first placed into a group including a large number of images that do not fit on a page. For example, ten images in Group B (FIG. 15) are taken in a short time interval such a day. The images in Group B can be further separated into page groups using other secondary criteria such as color content and image capture locations. For instance, the most popular color of each of the ten images can be plotted in a color space (such as (Y, u, v), (L, a, b) etc), as shown in FIG. 16. The color space is first separated into finite number of regions. The most popular color is defined as the color region that has the most pixel values that fall into. The ten images can be further sub-grouped according to their adjacencies in the color plane (u, v): images 1-3 may be categorized into a first group; images 4-6 may be categorized into a second group; images 7-10 may be categorized into a third group. The images 1-10 in Group A might have been taken within a same day. The photographer might have traveled to several different surroundings, such as a beach, a restaurant indoor, or a swimming pool at the hotel, each of which may have different color distributions. These different groups of images can be displayed on different page groups, as shown in FIG. 7B (step 1425). For example, in the user interface, image 1-3 can be bounded by a border 740 or 741 and to be assigned to Page 10. Images 4-6 can be displayed within the border 740 or 741 and to be assigned to Page 11. Images 7-10 can be placed within the border 740 or 741 and to be assigned to Page 12. It should be understood that the display of color content distributions of images are not limited to a specific color coordinates or the two dimensional color plane shown in FIG. 16. The color distributions can be plotted in three dimensional color spaces (Y, u, v), (L, a, b), or two dimensional color planes such as (Y, u), (Y, v), (a, b), (L, a) etc.

In some embodiments, the images can be sorted or grouped based on geographic locations. For example, assuming Group C (FIG. 15) includes five images that are taken, for example, in a same day. Geo location information about each of the five images can be extracted from the header information of the five images, and plotted as shown in FIG. 17. Images 1-3 are shown to have been taken in close proximity while images 4-5 are taken at similar locations. Images 1-3 can be sub-grouped together and assigned to Page 4 of the photo book. Images 4-5 can be sub-grouped together and assigned to Page 5 of the photo book. The two groups of images can be displayed in different borders 740, 741 on a user interface, as shown in FIG. 7B, to indicate that the images belong to different pages of a photo book. In some embodiments, the Images 1-3 and the Images 4-5 can be assigned to be on facing pages (e.g. such as pages 4 and 5) such that the images from the same events can be viewed on facing pages in one open-book view. The placements of two page groups of images on facing pages can be based on one or more secondary criteria, such as image capture time, image color content, and image capture location.

A library of page layouts are separately provided (step 1427). Next, a page layout is automatically selected from the library of page layouts in accordance with the properties of the images on the page as well as the text information associated with the image receiving areas in the page layout (step 1430). The format of the image receiving field in the page layout matches the format of the selected image. For example, images in Group A (FIG. 15) may include two landscape images (L) and two portrait images (P). A notation for the image formats for Group A can be “LLPP”. The page layout selected from the page-layout library should have four image receiving areas with matching image formats “LLPP”.

The page layout also includes an image caption area positioned adjacent to the image receiving area for receiving the associated text information. For example, one portrait image and one landscape image may be selected for the next page. The portrait image has associated text information entered by the user and stored in conjunction with the portrait image. The landscape is not associated with any text information. In selecting a page layout, the disclosed system first select page layouts containing two image receiving areas, and then further selects page layouts that have include one portrait and one landscape image receiving areas. Additionally, the disclosed system further selects page layouts that include an image caption area in association with the portrait image receiving area. After the page layout is selected, the selected image(s) and associated text are automatically placed in the selected page layout (step 1435). The placement of the selected image(s) and associated text can be done in a single step because they are pre-stored in an integrated data structure as described previously. The same steps can be repeated for fill the image fields and text fields in each page of a photo book. The user can select an image from the plurality of images to be used as part of the book cover. Finally, the photo book is created (step 1440).

It should be understood that the library of page layout contains layouts with different numbers of images other than one, two, and three. For a given number of images on a page and for the given formats of the images, the layout is not limited to the designs shown in this invention. There can be a large variation of layout designs for the same number of images with the same formats on each page. Moreover, the sorting and grouping of images can be implemented by other approaches or using other metrics. The illustration of page grouping and page breaks for the images can also vary within the scope of the present disclosure.
